Summary
The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the recipe block's 'summary' and 'notes' attributes in all versions up to, and including, 3.4.13. This is due to the 'WPZOOM_Helpers::deserialize_block_attributes' method converting unicode-encoded sequences back into HTML characters after sanitization has already been applied. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses the published post or the print view of an injected recipe.
